4 Technical 3 University of Denmark REPLI - DTU Renewable Energy Policy, Planning and Integration Advice Scientific advice within energy Scientific advice An integral part of Danish universities portfolio of activities 1/5 of DTU s staff are involved with scientific advice DTU is #2 in the world and #1 among the European universities in the category Energy Science and Engineering on the Academic Ranking of World Universities 2016 (Shanghai Jiao University) We have the expertise and the infrastructure. Goal The Sustainable Development Goal nr. 7. Means Collaboration between universities, companies, authorities and international organizations better technology and analysis methods within the energy sector.

5 Why advice on sustainable energy from DTU? REPLI provides research based advisory services and capacity building within integration of intermittent renewable energy sources. Our advisory services range from technology choices to policy advice and implementation.

6 The Kingdom of the Winds Wind share in Danish annual electricity consumption 45.8% 23 December 2017: 1 hour with 139% 25 December 2017: 1 day with average of 109% Political target 2050: The total energy supply based on renewable energy incl. heat, gas, transport, industry, etc. District heating: 50% share of total heat supply, with 69% CHP and <1% P2H

7 Flexibility Resources Finding ramping capabilities Supply flexibility Demand responds

8 Flexibility Resources Finding ramping capabilities Supply flexibility Sector coupling/ Electrification Demand responds

9 Sector coupling Electrification as source of flexibility Framework conditions Distribution of EU energy consumption (Source: EU Heating and Cooling strategy) Market design Direct regulation Fiscal policies Support schemes Grid regulation Large flexibility potentials in electrification of the energy sectors Hindered by regulatory barriers Remove barriers

10 Better Policies Accelerate Clean Energy Transition Insufficient market signals and uneven frameworks for different renewable energy resources limit flexibility Revise tariffs, taxation, and subsidies in Nordic-Baltic countries to increase flexibility Seven policy recommendations: R1: Create a level playing field for all RES across sectors through consistent fiscal policies; R2: Implement electricity grid tariffs which allow market signals for flexibility to reach the endusers; R3: Dynamic taxation of electricity (e.g. restructuring levies and taxes); R4: Encourage VRE operators to act flexibly using short-term market-based incentives; R5: Abolish RES support during negative price periods; R6: Enhance electrification by removing the limitations on using electricity for heating; R7: Tackle investment risks in flexible individual heating through new financing and private ownership models.

11 Unlocking flexible and sustainable energy systems Both technology deployment and regulatory changes Coherent changes in market designs, regulatory framework condition, and coupling of markets Make the sector coupling/electrification as flexible as possible Remove barriers Improve the business case for flexible power-to-heat/gas technologies Increase market integration and the value of VRE
